5.2 General notes on placing
The place of installation of a system is always determined during planning and noted in the system
documents. The following general planning notes, however, have to be read and complied with in
any case:
- Make sure that the construction (wall, pillar, ceiling construction, etc.) on which the devices
and/or system components will be mounted disposes of a sufficient load-carrying capacity
and is suitable for fixing (see Chapter 8. “Technical data“).
- Place the atomisers in such a way so as to enable the aerosol mist to spread freely. When the
aerosol mist is prevented from that by obstacles (e.g. ceilings, beams, etc.), build-up and
turbulences that may result in condensation occur.
- In the following illustration, you will find the measurements for the expansion of the aerosol
stream and the minimum distances that have to be kept. The measurements relate to the
maximum humidification capacity of the atomiser nozzles and a room temperature between
18° and 24°C (64 and 75°F). When the temperature is higher, the expansion of the aerosol stream is
reduced, when the temperature is lower, it increases.
- When atomiser nozzles are installed one opposite the other, make sure that the distance of at least
8 m (26 ft) is maintained between the nozzles in order to avoid that the aerosol streams
condensate each.
- Pay attention to the current of the room air. Do not install atomiser nozzles in the immediate
vicinity of an exhaust system or of a cold-air inlet.
- Do not direct atomiser nozzles at cold parts of a building, e.g. outside walls, windows, etc. (risk of
condensation).
- Insulate cold-water pipes in the area of the aerosol stream (risk of condensation).
- The evaporation process absorbs heat from the ambient air. For this reason, make sure that the
aerosol stream is not directed on persons or on places directly above workplaces.
- In order to guarantee an optimum humidification, ensure that the atomisers are sensibly
distributed in the room.
- The system components have to be mounted in such a way so as to provide for enough space
for operation and maintenance.
- Please contact NORTEC in case you have questions on the placement.
